Quite often laptop screens get damaged these can be replaced by me please call for details alternativeley purchase a new screen from ebay (Cheapest Place in Know) using model number on bottom of yopur laptop. I can then come and fit the screen for you.
Desktop Computer Monitors
I generally dont repair Computer Monitors but can check them for simple fixes suck as power issues, cable issues and some times what cn appear to be a monitor issue can be a problem with your tower.
If you require a new monitor I recommend using Novatech for replacements a very good supplier and usually offer 3 year guarantee on most monitors.
